Abstract

TRACK SKIPPER APPARATUS FOR VIDEO DISC PLAYER In a video disc player, a carriage is subject to translatory motion in correlation with radial motion of a playback stylus relative to a disc record. A stylus arm carrying the stylus at one end thereof has the other end pivotally secured to the carriage. A permanent magnet is mounted on the stylus arm near its free end. A pair of spaced coils having non-magnetic cores are disposed on the carriage such that the stylus arm-mounted magnet is interposed therebetween. The coils are selectively energized to change the radial location of the stylus relative to the record.
